停止 ASP.net MVC3 上的 JSON 附加，无效的 JSON 原语

Question

我在 Elmah 从堆栈中看到很多很多错误

System.ArgumentException
Invalid JSON primitive: .

，似乎代码从未到达我编写的代码的任何部分，所以我想知道为什么 ASP.net 引擎只是反序列化请求并给出错误，这是因为 http-header 暗示了类型是json？

ALL_RAW Connection: Keep-Alive Content-Length: 9101 Content-Type: application/json Content-Encoding: gzip

不管怎样，有没有办法改变MVC设置来停止回答这种请求（IP不断变化，URL不断变化，域名不断变化，所以现在我不知道如何阻止它:(
